Beta-Asp-(9)-Semaglutide is a semaglutide impurity. The amino acid at position 9 has been replaced by the beta-aspartic acid (also known as isoaspartic, isoAsp, β-Asp or beta-Asp). Semaglutide impurities are structurally related compounds that arise during synthesis, purification, or storage of semaglutide, a long-acting GLP-1 receptor agonist for managing type 2 diabetes and obesity.

Tetracosanoic acid is a drug product that is used in the development of drugs and as an analytical standard. Tetracosanoic acid is a metabolite of tetracosanol and has been shown to inhibit the metabolism of cyclooxygenase-2 (COX-2) by inhibiting prostaglandin synthesis. Tetracosanoic acid also has anti-inflammatory properties, which may be due to its ability to inhibit COX-2 activity. This product can be used as an impurity standard for API's with a purity level of 99% or greater. Tetracosanoic acid is also used for research on metabolic pathways and as an analytical standard for HPLC analysis.

Applications Anti-inflammatory. Selective cyclooxygenase-2 (COX-2) inhibitor.
